연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

Simultaneous determination of nine water-soluble vitamins contained in multi-nutrient tablets was carried out by reversed phase high-performance liquid chromatography (RP-HPLC) equipped with analytical $C_{18}$ column and UV (270 nm) detector. Those standard vitamins were successfully sep...

제안 방법

  • The objectives of this study were to purify the water­soluble vitamins of free forms from store-bought nutrient tablets after extraction with a Sep-Pak Cis cartridge, to find the method of analyzing at one time a lot of possible water­ soluble vitamins by reverse-phase column and UV de­tector, and finally to apply this analytical method to the analysis of multi-nutrient tablets from a local market.
  • Tlie other steps were the same as the analysis of water-soluble vitamins of the multinutrient tablets. The recovery yield was calculated in every experiment by measuring the amount of each standard vitamin of the added group and the amount of no added group. The recovery yield on the added amount of each standard vitamin was calculated by abstracting the peak area of no added group from that of the added vitamin group.
  • 25 um membrane filter, 10 uL of the filtrated solution was injected to HPLC. The recovery yields of the added water-soluble vitamins to multi-nutrient tablets were analyzed by the same method as the analysis of water-soluble vitamins in multinutrient tablets. The standard solution of each water-soluble vi­ tamin (0.

대상 데이터

  • The nutrient tablets used in this study were the com­mercial product of 'D' company and they were purchased from a local drug store. These multi-nutrient tablets mainly contained of several vitamins and other nutrients including minerals and dried-yeasts.
